This research paper investigates the bioconvection magneto
hydrodynamics (MHD) squeezing nanofluid flow between two parallel
plates. One of the plates is stretched and the other is kept fixed. In
this study the water is taken as a base fluid because it is a favorable fluid
for living microorganisms. Appropriate variables lead to a strong nonlinear ordinary differential system. The obtained nonlinear system has been
solved via homotopy analysis method (HAM). The significant influences
of thermophoresis and Brownian motion have also been taken in nanofluid
model. The convergence of the method has been shown numerically. The
variation of the Skin friction, Nusselt number, Sherwood number and their
effects on the velocity, concentration, temperature and the density motile
microorganism profiles are examined. It is observed that increasing thermal radiation augmented the temperature of the boundary layer area in
fluid layer. This increase leads to drop in the rate of cooling for nanofluid
flow. An interesting variation are inspected for the density of the motile
microorganisms due to the varying bioconvection parameter in suction and
injection cases. Furthermore, for comprehension the physical presentation
of the embedded parameters, such as unsteady squeezing parameter (λ )
, Thermal radiation parameter (Rd), Peclet number (Pe), Thermophoresis
parameter (Nt), Levis number (Le) , Prandtl number (Pr), Schmidt number (Sc)and Brownian motion parameter (Nb) are plotted and discussed
graphically. At the end, we made some concluding remarks in the light of
this research article.
